Workers have probably finished closing down westbound Loop 410 at Perrin Beitel by now so they can restripe the highway.

Crews will work through the night and into Saturday morning, likely interrupting the busy flow of weekend shoppers and travelers. Workers should finish by noon.

The $119 million project to widen this part of Loop 410 is the largest construction job in San Antonio, according to the Texas Department of Transportation. Work is slightly ahead of schedule and is expected to wrap up by the end of the year.

“We don’t have far to go,” TxDOT engineer Randy Grones assured. “The completion date is right around the corner.”

Starting tonight, workers plan to close both directions of Loop 410 on the Northeast Side through Saturday afternoon so they can set bridge beams.

Seems this morning’s heavy rain and thundery bluster might say otherwise, but the National Weather Service predicts sunny skies by Saturday, with a high at a mellow 73 degrees.

If the weather backs off as expected, crews will close all main lanes of Loop 410 at Perrin Beitel from 11 p.m. tonight to as late as 3 p.m. tomorrow, according to the Texas Department of Transportation. Motorists should use alternate streets such as Nacogdoches Road and Wurzbach Parkway, and Harry Wurzbach and Austin Highway.
